Medical Definition of Vertigo

Vertigo: Aside from being the name
of a classic 1958 Alfred Hitchcock film (with Jimmy Stewart
and Kim Novak), vertigo is a feeling that you are dizzily
turning around or that things are dizzily turning about
you. Vertigo is usually due to a problem with the inner
ear. Vertigo can also be caused by vision problems.

The word "vertigo" comes from the Latin "vertere", to
turn + the suffix "-igo", a condition = a condition of
turning about). Vertigo is medically distinct from
dizziness, lightheadedness, and unsteadiness. See:
